Vacuum oil filter is designed according to the principle of different boiling points of water and oil. It is composed of vacuum heating tank fine filter, condenser, primary filter, water tank, vacuum pump, oil discharge pump and electrical cabinet. The vacuum pump pumps out the air in the vacuum tank to form a vacuum. Under the action of atmospheric pressure, the external oil enters the primary filter through the inlet pipe to remove larger particles, and then enters the heating tank. After heating, the oil at 40~75°C passes through Automatic oil drift valve, this valve is to automatically control the amount of oil entering and exiting the vacuum tank to balance.
The heated oil is rapidly rotated by the spray wings to separate the oil into semi-mist, and the water in the oil evaporates rapidly into water vapor and is continuously sucked into the condenser by the vacuum pump. The water vapor entering the condenser is cooled and then returned to the original form of water and released. The oil in the vacuum heating tank is discharged into the fine filter by the oil discharge pump to filter out particulate impurities through oil filter paper or filter elements, thus completing the vacuum oil filter quickly. The whole process of removing impurities, water, and gas in the oil, so that the clean oil is discharged from the oil outlet out of the machine.
equipment performance
1. Vacuum system: It is composed of vacuum tank, vacuum pump, condensation tank, liquid accumulation tank and air supply system. The optimized structure design greatly increases the surface area of the oil in the vacuum system and maximizes the stroke of the oil in the vacuum system, so that the water and gas in the oil can be fully overflowed. This machine adopts an advanced anti-fog system, so that the oil filter will never have the oil spray phenomenon that is common in similar products when it is working.
2. Filtration system: Three-stage filtration is adopted, and the coarse filter at the oil suction port protects the oil pump and prolongs the service life of the main filter. There are two-stage fine filters behind the pump, so that the oil can quickly reach a high degree of cleanliness. The filter material is made of special graded pore glass fiber material, which can filter particles of different particle sizes in layers, which greatly improves the service life of the filter element. It has a perfect filter element structure, which can effectively reduce the surface velocity of the filter material and obtain stable filtration accuracy.
3. Heating system: Heating step by step is adopted, the surface heat load is less than 1.OW/cm2, and the oil will not deteriorate due to overheating. The oil temperature can be adjusted arbitrarily from 0 to 100°C. It is automatically controlled and equipped with a protection device. When the oil input is too small, it will automatically stop working to avoid damage to the heater caused by dry burning.
4. Automatic control system: This machine uses a series of automatic control instruments such as frequency converters, liquid level transmitters, temperature sensors, and vacuum sensors to collect various information about the operation of the equipment, which is processed by the central processor. Automatically control the operation of the entire equipment and monitor the operating status of the equipment. This machine is equipped with various protection devices (overload protection, overvoltage protection, phase sequence protection, abnormal operation shutdown protection), which can ensure the safe operation of the equipment.
5. Whole machine structure: The whole machine has an integrated bridge structure, which reduces the volume. The whole detachable oil tank is adopted to ensure oil-free operation on the ground and reduce environmental pollution. There are mobile, fixed, fully enclosed, vehicle-mounted and other models to choose from.
